This plugin requires the `manage_options` capability, meaning only administrators and users with similar permissions can access it. ### Can I view all plugins/themes at once? Yes! Select “All Plugins” or “All Themes” from the dropdown to view comprehensive structures of all installed items. ### How does the file viewer work? Non-image files open in a modal viewer within WordPress. Image files (JPG, PNG, GIF, etc.) automatically open in new browser tabs. ### What file types can I export? Structure Viewer supports four export formats: TXT (plain text), JSON (structured data), XML (standardized format), and PDF (formatted document with header and page numbers). You can also download any individual file directly from the file viewer modal. ### Is there a file size limit for viewing? Yes, for security and performance, the file viewer has a 1MB limit. Larger files should be accessed directly. ### Can I search within specific file types? Absolutely! Use the File Type filter to show only PHP files, JavaScript files, CSS files, images, or other specific file types. ### Does this work with WP-CLI? Yes! Structure Viewer includes WP-CLI commands: – `wp structure-viewer export < type> ` – Export structures via command line – `wp structure-viewer list < plugins|themes>` – List available items ### Is my data secure? Structure Viewer includes multiple security layers: nonce verification, path traversal prevention, capability checks, and input sanitization. ### What files are excluded from scans? By default: `node_modules`, `.git`, `.svn`, `.DS_Store`, log files, and system files are excluded for performance. ## Reviews ![](https://secure.gravatar.com/avatar/10afb29cb651cad3aa0de712d2b731f07da1bccb3cb97fa80229e9b25af7f86d? s=60&d=retro&r=g) ### 󠀁[A Must Have Plugin for Developers](https://wordpress.org/support/topic/a-must-have-plugin-for-developers-3/)󠁿 [timefighter11](https://profiles.wordpress.org/timefighter11/) March 23, 2026 1 reply As a web developer who audits and customizes a lot of third-party plugins/themes, this plugin has become must have for me for AI assisted development.
